Service Vehicle Soon Indicator: Description and Operation
SERVICE VEHICLE SOON INDICATOR
The SERVICE VEHICLE SOON indicator (amber) is an alert to the driver that the vehicle needs a non-emissions related repair. The indicator can be
turned ON, via a Class 2 message (the Body Function Controller (BFC) are the only computers that can illuminate this indicator at this time). The
indicator will also turn on whenever there are specific current codes stored in the Body Function Controller (BFC), or in the event of a loss of Serial
Peripheral Interface (SPI) data from the Body Function Controller (BFC) to the Instrument Cluster. Until the Body Function Controller (BFC) has been
programmed the Body Function Controller (BFC) will keep this indicator ON.
